I started using this one, i have yet to move off crunching rosetta workunits for hours... it doesn't seem to be getting any new workunits from the other projects i have active.

Maybe it's the new New CPU Scheduler? It should still switch projects though i would have thought.

EDIT: Don't use, this is in ALPHA testing. See here: http://boinc.berkeley.edu/alpha/

(i guess i need to go back a version now)
